The WINS service (wins.exe) on Microsoft Windows NT Server 4.0, Windows 2000 Server, and Windows Server 2003 allows remote attackers to write to arbitrary memory locations and possibly execute arbitrary code via a modified memory pointer in a WINS replication packet to TCP port 42, aka the "Association Context Vulnerability."

Microsoft Proxy Server 2.0 and Microsoft ISA Server 2000 (which is included in Small Business Server 2000 and Small Business Server 2003 Premium Edition) allows remote attackers to spoof trusted Internet content on a specially crafted webpage via spoofed reverse DNS lookup results.

The License Logging service for Windows NT Server, Windows 2000 Server, and Windows Server 2003 does not properly validate the length of messages, which leads to an "unchecked buffer" and allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, aka the "License Logging Service Vulnerability."
